Some research reported that the adhesive strength of thermal sprayed coating is associated with the fractal dimension of substrate surface. I want to know whether it is right based on my coating data. Can anyone suggest me a software or a method, which are used to calculate the fractal geometry of rough surface in 2D and 3D? I will appreciate if you tell me other methods or parameters can characterize the substrate or coating surface, excepting the roughness value Ra, Rq, wavelength, amplitude.
This paper, http://www.pnas.org/content/111/9/3298.full.pdf might be a good starting point. This one, http://arxiv.org/abs/1006.0601, might provide more technical details. Perhaps this one, https://www.rug.nl/research/portal/files/6669566/2003PhysRevEPalasantzas.pdf, might be of more direct relevance.
Thanks Stam Nicolis and Willem J Quadakkers for answers to this question.
Once you have a 2D picture in grey tones (which is, actually, a 3D fractal object) you can use FracLab to calculate its fractal dimension, as suggested by Mr. Gang Xiong. You find the adequate function right in the menu.
